WINDOW-SCREEN HOLDER. i

I A ucauon-me'd me 21;

Myiriirention relates to window screens,

and more particularly to the springsused with metal frame window screens.

There are various types of window screens having metal frames, to all of which my invention has direct application. There are hollow rectangular frames, of the type used in rewireable screens, round hollow frames, formed of a piece of metal bent to form a round bead, and the screen wire caught permanently between the two edges of the bent piece, and there are frames made of a piece of metal bent to form a frame, but not of tubular nature.

This last type, whichis of my own invention, is the one selected for purposes of illust-ration in the drawings, but it will be understood that no intent is present to confine my invention in screen frame springs to this particular form of molding.

The object of my invention is to provide a quickly demountable spring for screen frames, which will remain in place unless positively withdrawn, and to provide for as simple as possible a structure to accomplish the said purpose. The invention to some extent applies to any hollow molding which it is desired to equip with a spring.

This object and other advantages to be noted I accomplish by that certain construction and arrangement of parts to be hereinafter more specifically pointed out and claimed.

In the drawings:

Figure 1 is a perspective view of the device, in a form selected for illustration.

Figure 2 is a perspective of the same parts taken from another angle.

The screen frame 1 has a channel 2, into which wire gauze is to be clamped. in any desired manner, a central strengthening bend 3, and an outer edge wall 4. In placing; the screen into a window the walls 4 are set be tween such guides as are used for the screen, and form the side bearings for the screen upon which it slides inthe window frame.

Usually such screens are placed into rectangular channel members, and spring devices on the screens are seated in the channels or guides. A

It is required to have springs extending laterally from the outside edges or walls of the screen frame. In structures known to me the springs are usually spot welded, riv-- 11 and 12 at the ends.

eted or. screwed down ontoimetal screen moldings,when such are used.

The said outside wall of the screenlframes, are punched of whatever type-theymay be, out at three places, each punching out operation being in one direction so that all can be done at one time. The upper punch out is in the form of a three-sided out 5,

with the metal punched out bent down at 6 to form a tongue. The second is a slit necessary to cut out a tongue of metal 7, which is bent inwardly toa position 'Which should be away from the plane of the wall 4, sulficiently to leave a space, thick enough for the spring used to pass through it. The third cut is essentially a hole 8, punched out of the wall {1. The metal tongue shown at 9 is not essential, although it does away with the disposal of the punching.

The spring used is of ordinary type, having the how 10, and the partial return bends It is preferable that the end 12 be tapered off somewhat to readily enter and slide in'the hole 8.

The bend 11, in the form illustrated, is cut with a hole 13, to fit over the tongue 6.

As so constructed the spring is set in place by inserting the end 11 between the tongue 7 and the wall 4, and setting the hole 13 over 'A SSIG NO R TO THE NATIONAL SCREEN PATENT FFICE;

the tongue 6. The spring is then contracted and the end 12 is thrust through the hole 8.

This forms a permanent mounting for the spring. Any flattening of the spring is taken up by the-end 12sliding in the hole 8. The flattening has a tendency also to force the eye 13 more tightly over the tongue 6, since the return bend resting on the tongue 7, acts as a fulcrum and tilts up the end of the spring.v

The position-of the tongue 7 is thus of importance, as it should not be such that this fulcrum action cannot take place. Aten- .dency to slide lengthwise of the spring at this point, not accompanied'by the tendency to tilt up at the end would displace the spring end from the tongue 6. The spring end at 12 must be held down to get It may be observed that p at the end of the spring instead of the hole, could be used to engage a hole formed in the wall 4 of the screen molding, instead ofthe lip being turned down from the molding, and the hole being formed in the spring.

the best action. a a lip turned up A This is so obvious a reversal of action to the same end, that it is not deemed necessary to illustrate it.

It is essential that the end of the spring at 11 should lie more or less in the plane of the wall 4, and not slant inwardly of the molding, from the wall 4.

Having thus described my invention in a selected embodiment, what I claim as novel therein, and desire to secure by Letters Patent, is

A frame having an external edge formed as a channel, said channel having an external bearing face and said channel provided with a slit extending across said face, a tongue 15 in said channel turned inwardly from said face, said tongue being formed from one of the edges of the slit portion of said channel, a leaf spring for said screen extending through said slit with a tongue projecting inwardly beyond the slit and a-slot in the spring to engage said tongue with a bearing for the spring on the first mentioned tongue to secure said spring to the inner face of said channel, said spring having a main bend, a

slot in said channel and the end of the sprin opposite the end adapted to be interengagle within the channeladapted to slide wit in said slot.
